I turned down sex on the train on the way back from Cardiff. Am still trying to work out if the main reason was because...
a) He wasn't pretty.
b) I was hungover.
c) Train toilets? On a Sunday morning? Euw.
d) I was at a really good bit in Alias (oh! my! god! Sark's back)
e) My undying love for my not-boyfriend.
f) These things are just too tacky.
Oh dear. I've got the suspicion it was "a".
